8 Claims. (Cl. 206-62) This invention appertains to the l'packaging offragile articles, and more particularly to a novel carton for shippingcurved windshields and like glass of the socalled panoramic orwrap-around type.

In my co-pending application, Serial No. 441,991, filed July 8, 1954,now matured into Patent No. 2,776,745 on January 8, 1957, I illustratedand claimed a novel cushioning strip for the edge of panoramicwindshields and like glass, with insertable corner cushioning and fillerstrips for supporting the curved wings of the glass.

One of the primary objects of Vmy invention is to provide a novel cartonhaving as an integral part thereof means for effectively providingcorner cushioning and filler blocks for supporting the curved terminalsof automobile glass in a desired manner.

Another salient object of my invention is to provide means whereby thecorner cushioning and filler blocks are connected with the body of thecarton so that slipping and displacement of such blocks is prevented.

A further important object of my invention is to provide a shippingcarton having extensions on the top and bottom end flaps thereof, withthe extensions so arranged that the same can be readily folded duringthe setting up of the carton, and detachably connected with the closureflaps of the carton for forming the desired cushioning and filler blocksat the correct points.

A still further object of my invention is the provision of means formedon the inner closure flap of the carton of a resilient nature forengaging and holding the cushioning strip for the edge of the glass inproper piace upon the closing and sealing of the carton.

With these and other objects in view, the invention consists in thenovel construction, arrangement and formation of parts, as will behereinafter more specifically described and claimed, and illustrated inthe accompanying drawings, in which drawings, g

Figure 1 is a vertical longitudinal sectional View through a completecarton showing the saine in its closed position, with a panoramicwindshield or like glass therein, the view illustrating the novelcushioning and corner blocks, and the resilient flange on the top innerclossure ap for engaging the peripheral cushion strip; i

Figure 2 is an enlarged fragmentary detail longitudinal sectional viewthrough one uper corner of the carton, with the carton in its foldedcondition, the glass being shown removed` for the purpose of simplicity,the section being taken on the line 2-2 of Figure 3, looking in thedirection of the arrows;

Figure 3 is a fragmentary transverse sectional view through the cartontaken on the line 3--3 of Figure 2, looking in the direction of thearrows;

Figure 4 is a perspective View of the carton in its set up conditionready to receive a panoramic windshield or the like, with a peripheralcushioning strip thereabout;

Figure 6 is a View similar to Figures 4 and 5, but showing the carton inits complete closed, sealed position, parts of the figure being shownbroken away and in section;

Figure 7 is a top plan view of the blank from which the carton is made;

Figure 8 is a fragmentary detail perspective view illustrating aslightly modified form of the carton, the carton being shown in its setup condition but prior to the closing and sealing thereof;

Figure 9 is a view similar to Figure 8, but showing the carton in itspartially closed position, and

Figure 10 is a detail fragmentary perspective view illustrating anotherand preferred form of the bent resilient flange on the inner closureiiap of the carton for engaging and holding the peripheral cushioningstrip of the glass.

Referring to the drawings in detail, wherein similar referencecharacters designate corresponding parts throughout the several views,the letter C generally indicates my improved carton and B (Figure 7) ablank from which the carton can be formed.

The carton C includes like side walls 15 and 16 connected by an end wall17. Referring to Figure 7, it can be seen that the blank B is scoredlongitudinally, as at 18, to define the side walls 15 and 16, and scoredtransversely, as at 19, to define the connecting end wall 17. Onetransverse edge of the side wall 15 has formed thereon an end wall 20,and this end wall is defined by a transverse score line 21.

Now referring to the blank B, from the description so far, it can beseen that the blank is first folded on the score lines 19 so that thewalls 15 and 16 will project at right angles therefrom, and in spacedparallel relation to one another, after which the end flap 20 is bent onthe score ine 21 at right angles to the side wall 15 and parallel to theend wall 17. At this time, the free edge of the end wall 20 can besecured to the outer edge of the end wall 16 by heavy adhesive tape.Formed on the longitudinal edges of the side wall 15 and defined by thelongitudinal score lines 18 are inner top and bottom closure flaps 22and 23, and these flaps are adapted to be bent inwardly over the sidewalls on said score lines 18. Formed on the longitudinal edges of theside wall 16 are top and bottom outer closure flaps 24 and 25. Thesefiaps are also adapted to bent inwardly on the longitudinal score lines18.

Now in accordance with my invention, the upper and lower edges of theend Walls 17 and 20 have formed thereon extensions 26, 27, 28 and 29. Byreferring to Figure 7, it can be seen that the extensions 26 and 27 arecarried by the top and bottom transverse edges of the end wall 17, andthat the extensions 28 and 29 are carried by the upper and lowertransverse edges of the end wall 20 and that the extensions areinitially bent inwardly on the score lines 18.

All of the extensions 26, 27, 28 and 29 are scored transverselyintermediate their opposite ends, as at 30, and these score lines 30define means for facilitating the bending of the extensions intermediatetheir ends to define inwardly projecting substantially V-shapedcushioning corner blocks for supporting the glass at the curved wingedterminals thereof, as will later appear. The score lines 30 are onlyused to facilitate the bending of the extensions 26, 27, 28 and 29;however, in the blank, these score lines extend longitudinally of theentire blank, in

that it is easier to score the blank in its entirety than to merelyscore the extensions 30. Consequently, the score lines 30 on the closureflaps 22, 23, 24 and 25 serve no useful function.

The extensions 26, 27, 28 and 29 are also scored or weakenedtransversely adjacent to, but spaced from their outer ends, as at 31,and these score lines 31 are disposed a considerable distance from thescore lines 30. The edges of these extensions are provided with inwardlydirected spaced slots 32 and the score lines 31, in conjunction with theslots 32, define a central tongue 33 and side tabs 34. The tabs 34 arebent on the score lines 31 for a purpose, which will later appear. Thescore lines 31 can extend the full length of the blank B to lower thecost of manufacture.

Now considering that the blank B is partially folded and set up toprovide the spaced parallel side walls and 16, and the end walls i7 and18, then the bottom inner ap 23 is folded inwardly over the foldedextensions 27 and 29 and at this time the central tongues 33 of theseextensions are inserted in transversely extending slots 35 cut in thebottom Wall flap 23 and the side tabs 34 are bent on their score lines31 and placed on the inner surface of the inner wall ap. The outerbottom wall ap 2S is now folded into place and secured in position by asuitable adhesive or adhesive tape. The desired glass, such as apanoramic windshield W (see Fig. l), is now ready to be placed in thecarton C and the edge of this glass is encased in a cushioning andpackaging strip S. This strip S is illustrated, described and claimed inmy mentioned, co-pending application. The folded extensions 27 and 29abut the cushioning strip and these extensions form cushioning fillerblocks for the lower corners of the wings of the windshield W.

The carton is now ready to be sealed and the inner top wall ilap 22 isfolded down with the extensions 26 and 28 folded into their desiredshape. The tongues 33 on the extensions 26 and 28 will pass throughtransversely extending slots 36 cut in the inner top wall flap 22 andthe side tabs 34 of these extensions rest against the inner surface ofthis inner top wall flap. The outer top wall flap 2d is then folded overthe inner flap 22 and is sealed in position by a suitable adhesive orheavy adhesive tape. The folded extensions 26 and 28 engage thecushioning strip S and function to hold the strip in place and thefolded extensions define corner cushioning blocks for supporting theupper ends of the wings of the windshield W.

The entire structure forms an effective means for holding the glass inthe carton against movement and breakage and the folded extensions aresecurely held in place against displacement and these extensions absorbshock and admirably perform their function of filler blocks. Theextensions are so-shaped as to conform to the configuration of thewindshield or other glass being shipped and it is to be noted that thelower folded extensions 27 and 29 are of a slightly different shape thanthe upper folded extensions 26 and 28.

Inorder to further aid in holding the cushioning strip S in place at thetop of the glass and to give an additional resilient support, the innertop wall flap 22 can have bent down therefrom on its longitudinal edge aflexible wing 37 and upon the bending inwardly of this wing the samewill engage the strip S, as best shown in Figure l, and hold the stripin place. The wing 37 (see Figure 7), can be defined by a part of one ofthe longitudinally extending score or weakening lines 31 and inwardlydirected slots 39. The slots 39 extend inwardly from the Vinner edge ofthe flap 22 to the score line 31. This wing 37 can take different forms,as will be later set forth.

This wing 37 has also another important function namely, upon thepacking of the glass in the carton, the glass can be convenientlyinspected at different points during transit, by merely breaking theseal for the outer top wall flap and by lifting up the wing 37. Afterinspection the wing 37 can be lowered and the outer top wall flap can beswung back in place and sealed by tape. By operating the wing 37, it isunnecessary to disturb the l tongues 33 of the transversely extendingcushioning members.

The ends of the extensions 26, 27, 23 and 29 can be detachably connectedwith the inner bottom and top wall flaps 23 and 22, in different ways,and in Figures S and 9, I have shown another of these ways. In thisform, the inner bottom and top Wall flaps are slotted transversely theirentire width, as at 40, and the extensions instead of being providedwith central tongues and side tabs, are provided with a continuoustransversely extending tongue This tongue 41 is inserted in the slot d@upon the folding of the blank.

In Figure l0, I have shown another means for engaging the cushioningstrip S along the top edge of the glass and in this form the inner topflap between the slots 4G is folded to provide a longitudinallyextending tube 42 of a square shape in cross-section. The tube extendsinto the body of the carton and against the adjacent portion ofcushioning strip S.
